Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0043] The discretization of the target area involved in the present invention refers to the method of subdividing the target area and discretizing it into a collection of simple geometric simplexes, and the small areas that have been discretized are discrete primitives.

[0044] The triangulation mentioned in the present invention refers to dividing the target area into a set of triangular primitives. The square subdivision refers to dividing the target area into a set of square primitives. Rasterization is a method to convert the target area (vector map) into raster data (square).

[0045] The present invention relates to vectorization technology: mainly researches the process of transforming simple geometric simplex sets into vectorized graphics. Vectorized graphics have some excellent properties. It is composed of some simple and basic ge...

Abstract

The invention discloses a simulative division method and a simulative division system for cell coverage. The method comprises the following steps that: after performing discretization on a target area, and then acquiring the coverage diagram of the cell through a free space of a single cell, the system acquires a combined coverage diagram of a plurality of cells; and the system performs vector processing on the acquired combined coverage diagram of the plurality of cells by means of boundary following and key point fitting to acquire the simulative division of the coverage corresponding to each cell. By using the invention, the problems that the conventional cell coverage simulative division algorithm based on Voroni diagram is low in accuracy, and a large amount of data is generated in the cell coverage simulative division based on field intensity are solved.

Description

technical field [0001] The invention relates to the field of mobile communication networks, in particular to a method and system for wireless cell coverage simulation division. Background technique [0002] In the optimization work of mobile communication network, how to express the geographical coverage area of ​​each wireless cell in an intuitive and accurate way, and thus intuitively obtain the handover or reselection relationship between the cell and the surrounding cells It is a basic work of network optimization. This plays a very important auxiliary role in many topics including adjacent cell planning analysis and optimization, coverage analysis, and handover analysis for higher business layer topics. As the wireless network optimization work has higher and higher requirements for the accuracy of the simulated coverage area of ​​the wireless cell, the traditional Voronoi diagram-based cell coverage simulation partition map can no longer meet the accuracy requirements...
